2 Logging In to the System as root以root身份登录系统，图形化安装，安装系统时需安装系统桌面相关支持软件包。注意设置好相关环境变量后，需root执行xhost ，切换到oracle用户安装软件时菜能使用桌面图形环境！ Before you install the Oracle software, you must complete several tasks as the root user. To log in as the root user, complete one of the following procedures:
Note: You must install the software from an X Window System workstation, an X terminal, or a PC or other system with X server software installed
- Following are the steps for installing the software from an X Window System workstation or X terminal:
- Start a local terminal session, for example, an X terminal (xterm).
- If you are not installing the software on the local system, then enter the following command to enable the remote host to display X applications on the local X server:
$ xhost fully_qualified_remote_host_nameFor example:
$ xhost somehost.us.example.com - If you are not installing the software on the local system, then use the ssh, rlogin, or telnet command to connect to the system where you want to install the software:
$ telnet fully_qualified_remote_host_name - If you are not logged in as the root user, then enter the following command to switch user to root:
$ sudo sh password: #
- Following are the steps for installing the software from a PC or other system with X server software:
Note: If necessary, refer to your X server documentation for more information about completing this procedure. Depending on the X server software that you are using, you may have to complete the tasks in a different order.
- Start the X server software.
- Configure the security settings of the X server software to permit remote hosts to display X applications on the local system.
- Connect to the remote system where you want to install the software and start a terminal session on that system, for example, an X terminal (xterm).
- If you are not logged in as the root user on the remote system, then enter the following command to switch user to root:
$ sudo sh password: #
3 Checking the Hardware Requirements
系统硬件环境检查：内存、swap、磁盘空间，系统内核等检查 The system must meet the following minimum hardware requirements:
3.1 Memory RequirementsThe following are the memory requirements for installing Oracle Database 11g Release 2 (11.2):
- Minimum: 1 GB of RAM
Recommended: 2 GB of RAM or more
To determine the RAM size, enter the following command:
# grep MemTotal /proc/meminfo If the size of the RAM is less than the required size, then you must install more memory before continuing.
- The following table describes the relationship between installed RAM and the configured swap space recommendation:
Note: On Linux, the HugePages feature allocates non-swappable memory for large page tables using memory-mapped files. If you enable HugePages, then you should deduct the memory allocated to HugePages from the available RAM before calculating swap space.
Available RAM | Swap Space Required | Between 1 GB and 2 GB | 1.5 times the size of the RAM | Between 2 GB and 16 GB | Equal to the size of the RAM | More than 16 GB | 16 GB |
- To determine whether the system architecture can run the software, enter the following command:
# uname -m Note: This command displays the processor type. Verify that the processor architecture matches the Oracle software release to install. If you do not see the expected output, then you cannot install the software on this system.
To determine the size of the configured swap space, enter the following command:
# grep SwapTotal /proc/meminfoIf necessary, refer to the operating system documentation for information about how to configure additional swap space.
To determine the available RAM and swap space, enter the following command:
# freeIMPORTANT: - Oracle recommends that you take multiple values for the available RAM and swap space before finalizing a value. This is because the available RAM and swap space keep changing depending on the user interactions with the computer.
- Contact your operating system vendor for swap space allocation guidance for your server. The vendor guidelines supersede the swap space requirements listed in this guide.
Automatic Memory Management Starting with Oracle Database 11g, the Automatic Memory Management feature requires more shared memory (/dev/shm)and file descriptors. The shared memory should be sized to be at least the greater of MEMORY_MAX_TARGET and MEMORY_TARGET for each Oracle instance on that computer.
To determine the amount of shared memory available, enter the following command:
# df -h /dev/shm/Note: MEMORY_MAX_TARGET and MEMORY_TARGET cannot be used when LOCK_SGA is enabled or with HugePages on Linux.
3.2 System ArchitectureTo determine whether the system architecture can run the software, enter the following command:
# uname -mNote: This command displays the processor type. Verify that the processor architecture matches the Oracle software release to install. If you do not see the expected output, then you cannot install the software on this system.
3.3 Disk Space RequirementsThe following are the disk space requirements for installing Oracle Database 11g Release 2 (11.2):
- At least 1 GB of disk space in the /tmp directory
To determine the amount of disk space available in the /tmp directory, enter the following command:
# df -h /tmp If there is less than 1 GB of free disk space available in the /tmp directory, then complete one of the following steps:
- Delete unnecessary files from the /tmp directory to meet the disk space requirement.
- Set the TMP and TMPDIR environment variables when setting the oracle user's environment.
See Also: "Configuring the oracle User's Environment"for more information about setting TMP and TMPDIR
- Extend the file system that contains the /tmp directory. If necessary, contact the system administrator for information about extending file systems.
- To determine the amount of free disk space on the system, enter the following command:
# df -h - The following tables describe the disk space requirements for software files, and data files for each installation type on Linux x86-64:
Installation Type | Requirement for Software Files (GB) | Enterprise Edition | 4.35 | Standard Edition | 4.22 |
Installation Type | Requirement for Data Files (GB) | Enterprise Edition | 1.7 | Standard Edition | 1.5 |
Additional disk space, either on a file system or on an Oracle Automatic Storage Management disk group is required for the fast recovery area if you choose to configure automated backups.
4 Checking the Software Requirements
Depending on the products that you intend to install, verify that the following softwares are installed on the system.

5 Creating Required Operating System Groups and UsersThe following local operating system groups and users are required if you are installing Oracle Database:
The Oracle Inventory group (typically, oinstall) The OSDBA group (typically, dba) The Oracle software owner (typically, oracle) The OSOPER group (optional. Typically, oper)
To determine whether these groups and users exist, and if necessary, to create them, follow these steps:
- To determine whether the oinstall group exists, enter the following command:
# more /etc/oraInst.loc If the output of this command shows the oinstall group name, then the group exists.
If the oraInst.loc file exists, then the output from this command is similar to the following:
inventory_loc=/u01/app/oraInventory inst_group=oinstall The inst_group parameter shows the name of the Oracle Inventory group, oinstall.
- To determine whether the dba group exists, enter the following command:
# grep dba /etc/group If the output from this commands shows the dba group name, then the group exists.
- If necessary, enter the following commands to create the oinstall and dba groups:
# /usr/sbin/groupadd oinstall # /usr/sbin/groupadd dba - To determine whether the oracle user exists and belongs to the correct groups, enter the following command:
# id oracle If the oracle user exists, then this command displays information about the groups to which the user belongs. The output should be similar to the following, indicating that oinstall is the primary group and dba is a secondary group:
uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper) - If necessary, complete one of the following actions:
- If the oracle user exists, but its primary group is not oinstall or it is not a member of the dba group, then enter the following command:
# /usr/sbin/usermod -g oinstall -G dba oracle - If the oracle user does not exist, enter the following command to create it:
# /usr/sbin/useradd -g oinstall -G dba oracle This command creates the oracle user and specifies oinstall as the primary group and dba as the secondary group.
- Enter the following command to set the password of the oracle user:
# passwd oracle
6 Configuring Kernel Parameters
系统内核参数设置
Verify that the kernel parameters shown in the following table are set to values greater than or equal to the minimum value shown. The procedure following the table describes how to verify and set the values. Note: The kernel parameter and shell limit values in this section are minimum values only. For production database systems, Oracle recommends that you tune these values to optimize the performance of the system. Refer to your operating system documentation for more information about tuning kernel parameters.
Parameter | Minimum Value | File | semmsl semmns
semopm
semmni
| 250 32000
100
128
| /proc/sys/kernel/sem | shmall | 2097152 | /proc/sys/kernel/shmall | shmmax | Minimum: 536870912 Maximum: A value that is 1 byte less than the physical memory
Recommended: More than half the physical memory
See My Oracle Support Note 567506.1 for additional information about configuring shmmax.
| /proc/sys/kernel/shmmax | shmmni | 4096 | /proc/sys/kernel/shmmni | file-max | 6815744 | /proc/sys/fs/file-max | ip_local_port_range | Minimum: 9000 Maximum: 65500
| /proc/sys/net/ipv4/ip_local_port_range | rmem_default | 262144 | /proc/sys/net/core/rmem_default | rmem_max | 4194304 | /proc/sys/net/core/rmem_max | wmem_default | 262144 | /proc/sys/net/core/wmem_default | wmem_max | 1048576 | /proc/sys/net/core/wmem_max | aio-max-nr | 1048576 Note: This value limits concurrent outstanding requests and should be set to avoid I/O subsystem failures.
| /proc/sys/fs/aio-max-nr |
Note: If the current value of any parameter is higher than the value listed in this table, then do not change the value of that parameter.
To view the current value specified for these kernel parameters, and to change them if necessary: - Enter commands similar to the following to view the current values of the kernel parameters:
Note: Make a note of the current values and identify any values that you must change.
Parameter | Command | semmsl, semmns, semopm, and semmni | # /sbin/sysctl -a | grep sem This command displays the value of the semaphore parameters in the order listed.
| shmall, shmmax, and shmmni | # /sbin/sysctl -a | grep shm | file-max | # /sbin/sysctl -a | grep file-max | ip_local_port_range | # /sbin/sysctl -a | grep ip_local_port_range | rmem_default | # /sbin/sysctl -a | grep rmem_default | rmem_max | # /sbin/sysctl -a | grep rmem_max | wmem_default | # /sbin/sysctl -a | grep wmem_default | wmem_max | # /sbin/sysctl -a | grep wmem_max |
- If the value of any kernel parameter is different from the recommended value, then complete the following steps:
- Using any text editor, create or edit the /etc/sysctl.conf file, and add or edit lines similar to the following:
Note: Include lines only for the kernel parameter values to change. For the semaphore parameters (kernel.sem), you must specify all four values. However, if any of the current values are larger than the minimum value, then specify the larger value.
fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 By specifying the values in the /etc/sysctl.conf file, they persist when you restart the system. However, on SUSE Linux Enterprise Server systems, enter the following command to ensure that the system reads the /etc/sysctl.conf file when it restarts:
# /sbin/chkconfig boot.sysctl on - Enter the following command to change the current values of the kernel parameters:
# /sbin/sysctl -p Review the output from this command to verify that the values are correct. If the values are incorrect, edit the /etc/sysctl.conf file, then enter this command again.
- Enter the command /sbin/sysctl -a to confirm that the values are set correctly.
- On SUSE systems only, enter the following command to cause the system to read the /etc/sysctl.conf file when it restarts:
# /sbin/chkconfig boot.sysctl on - On SUSE systems only, you must enter the GID of the oinstall group as the value for the parameter /proc/sys/vm/hugetlb_shm_group. Doing this grants members of oinstall a group permission to create shared memory segments.
For example, where the oinstall group GID is 501:
# echo 501 > /proc/sys/vm/hugetlb_shm_group After running this command, use vi to add the following text to /etc/sysctl.conf, and enable the boot.sysctl script to run on system restart:
vm.hugetlb_shm_group=501 Note: Only one group can be defined as the vm.hugetlb_shm_group.
- After updating the values of kernel parameters in the /etc/sysctl.conf file, either restart the computer, or run the command sysctl -p to make the changes in the /etc/sysctl.conf file available in the active kernel memory.
Check Resource Limits for the Oracle Software Installation Users For each installation software owner, check the resource limits for installation, using the following recommended ranges:
Table 1 Installation Owner Resource Limit Recommended Ranges Resource Shell Limit | Resource | Soft Limit | Hard Limit | Open file descriptors
| nofile
| at least 1024
| at least 65536
| Number of processes available to a single user
| nproc
| at least 2047
| at least 16384
| Size of the stack segment of the process
| stack
| at least 10240 KB
| at least 10240 KB, and at most 32768 KB
|
To check resource limits:
- Log in as an installation owner.
- Check the soft and hard limits for the file descriptor setting. Ensure that the result is in the recommended range. For example:
$ ulimit -Sn 4096 $ ulimit -Hn 65536 - Check the soft and hard limits for the number of processes available to a user. Ensure that the result is in the recommended range. For example:
$ ulimit -Su 2047 $ ulimit -Hu 16384 - Check the soft limit for the stack setting. Ensure that the result is in the recommended range. For example:
$ ulimit -Ss 10240 $ ulimit -Hs 32768 - Repeat this procedure for each Oracle software installation owner.
If necessary, update the resource limits in the /etc/security/limits.conf configuration file for the installation owner. For example, add the following lines to the /etc/security/limits.conf file:
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240
Note: - The values mentioned in this example are illustrative and not actual values that must be added.
- When the limits.conf file is changed, these changes take effect immediately. However, if the grid or oracle users are logged in, then these changes do not take effect until you log these users out and log them back in. You must do this before you attempt to use these accounts to install.
7 Creating Required DirectoriesCreate directories with names similar to the following, and specify the correct owner, group, and permissions for them:
The Oracle base directory must have 3 GB of free disk space, or 4 GB of free disk space if you choose not to create a separate Oracle data file directory.
Note: If you do not want to create a separate Oracle data file directory, then you can install the data files in a subdirectory of the Oracle base directory. However, this is not recommended for production databases.
To create the Oracle base directory:
- Enter the following command to display information about all mounted file systems:
# df -k This command displays information about all the file systems mounted on the system, including:
The physical device name The total amount, used amount, and available amount of disk space The mount point directory for that file system
- From the display, identify either one or two file systems that meet the disk space requirements mentioned earlier in this section.
- Note the name of the mount point directory for each file system that you identified.
- Enter commands similar to the following to create the recommended subdirectories in the mount point directory that you identified and set the appropriate owner, group, and permissions on them:
# mkdir -p /mount_point/app/ # chown -R oracle:oinstall /mount_point/app/ # chmod -R 775 /mount_point/app/ For example:
# mkdir -p /u01/app/ # chown -R oracle:oinstall /u01/app/ # chmod -R 775 /u01/app/
8 Configuring the oracle User's Environment
创建oracle用户以及用户组并配置环境变量
You run Oracle Universal Installer from the oracle account. However, before you start Oracle Universal Installer, you must configure the environment of the oracle user. To configure the environment, you must:
- Set the default file mode creation mask (umask) to 022 in the shell startup file.
- Set the DISPLAY environment variable.
To set the oracle user's environment:
- Start a new terminal session, for example, an X terminal (xterm).
- Enter the following command to ensure that X Window applications can display on this system:
$ xhost fully_qualified_remote_host_nameFor example:
$ xhost somehost.us.example.com - If you are not logged in to the system where you want to install the software, then log in to that system as the oracle user.
- If you are not logged in as the oracle user, then switch user to oracle:
$ su - oracle - To determine the default shell for the oracle user, enter the following command:
$ echo $SHELL - To run the shell startup script, enter one of the following commands:
Bash shell: $ . ./.bash_profileBourne or Korn shell: $ . ./.profileC shell: % source ./.login
- If you are not installing the software on the local computer, then run the following command on the remote computer to set the DISPLAY variable:
In this example, local_host is the host name or IP address of the local computer to use to display Oracle Universal Installer.
Run the following command on the remote computer to check if the shell and the DISPLAY environmental variable are set correctly:
echo $SHELL echo $DISPLAY Now to enable X applications, run the following commands on the local computer:
$ xhost fully_qualified_remote_host_nameTo verify that X applications display is set properly, run a X11 based program that comes with the operating system such as xclock:
$ xclock In this example, you can find xclock at /usr/X11R6/bin/xclocks. If the DISPLAY variable is set properly, then you can see xclock on your computer screen.
See Also: PC-X Server or operating system vendor documents for further assistance - If you determined that the /tmp directory has less than 1 GB of free disk space, then identify a file system with at least 1 GB of free space and set the TMP and TMPDIR environment variables to specify a temporary directory on this file system:
- To determine the free disk space on each mounted file system use the following command:
# df -h /tmp - If necessary, enter commands similar to the following to create a temporary directory on the file system that you identified, and set the appropriate permissions on the directory:
$ sudo mkdir /mount_point/tmp $ sudo chmod a wr /mount_point/tmp # exit - Enter commands similar to the following to set the TMP and TMPDIR environment variables:
- Enter commands similar to the following to set the ORACLE_BASE and ORACLE_SID environment variables:还是环境变量设置
In this example, /u01/app/oracle is the Oracle base directory that you created or identified earlier and sales is the database name (typically no more than five characters).- Enter the following commands to ensure that the ORACLE_HOME and TNS_ADMIN environment variables are not set:
Note: If the ORACLE_HOME environment variable is set, then Oracle Universal Installer uses the value that it specifies as the default path for the Oracle home directory. However, if you set the ORACLE_BASE environment variable, then Oracle recommends that you unset the ORACLE_HOME environment variable and choose the default path suggested by Oracle Universal Installer.
9 Mounting the Product Disc
挂载oracle光盘或者ISO镜像开始安装
